Kugwiritsa ntchito hydroxypropyll methylcellulose ku gypsum

Hydroxypropyl methylcellulose (hpmc)ndiowonjezera omwe amagwiritsidwa ntchito pomanga zida zomangira, makamaka pazogulitsa zama gypsum. HPMC ili ndi chikalata chabwino chamadzi, chokulirapo, mkaka ndi kutsatira, ndikupangitsa kukhala chinthu chofunikira kwambiri muzogulitsa gypsum.

1. Udindo wa HPMC ku gypsum

Kuwongolera Kusunga Madzi

HPMC ili ndi mayamwidwe abwino kwambiri ndi madzi osasunga madzi. Mukamagwiritsa ntchito mankhwala a gypsum, kuwonjezera kuchuluka kwa HPMC yoyenera kuchepetsedwa kwa madzi, kukonzanso kugwirira ntchito gypsum slurry, musakhale onyowa kwa nthawi yayitali pomanga, ndikupewa kuwonongeka chifukwa cha madzi obwera mwachangu.

Kusinthana kwamiyendo ndi malo otsutsa

HPMC imapatsa gypsum slurry code catery, kulola kuti atsatire mwamphamvu makoma kapena magawo ena. Zida za gypsum zimapangidwa pamiyeso yolumikizira, kukula kwakukuru kwa HPMC kumachepetsa kusamba ndikuwonetsetsa kuti pali kufanana komanso kuwunika.

Sinthani magwiridwe antchito

HPMC imapangitsa gypsum slurry kukhala kosavuta kugwiritsa ntchito ndikufalikira, imathandizira kugwira ntchito yomanga, ndikuchepetsa zinyalala zakuthupi. Kuphatikiza apo, zingathenso kuchepetsa mikangano pakumanga, kupangitsa kuti zisakhale zosavuta komanso zosavuta pomanga ogwira ntchito.

Sinthani kukana

Pazogulitsa zamagulu a gypsum zinthu, madzi osasinthika amatha kuyambitsa pansi. HPMC imapanga gypsum hydrate yunifolomu yambiri kudzera mu magwiridwe ake abwinobwino pamadzi, potero kuchepetsa mapangidwe a ming'alu ndikuwongolera mtundu wonse wa chinthu chomaliza.

Kutengera pa nthawi yophatikiza

HPMC ikhoza kukulitsa nthawi yogwira ntchito ya gypsum, kulola ogwira ntchito zomanga kukhala ndi nthawi yokwanira kusintha ndi kudula, ndikupewa kulephera kofulumira chifukwa cha kuchuluka kwa gypsum.

2. Kugwiritsa ntchito HPMC muzogulitsa zosiyanasiyana za gypsum

Gypsum popereka

Mu gypsum zojambula zojambula, ntchito yayikulu ya HPMC ndikuwongolera kusungidwa kwamadzi ndikuwongolera magwiridwe antchito, kotero kuti gypsum yomwe gypsum imatha kutsata khoma, kuchepetsa kusokonekera, ndikusintha mtundu wazomanga.

Gypsum putty

HPMC imatha kusintha utoto ndi kusalala kwapakuti, pomwe kukulitsa kutsatira, ndikupangitsa kukhala koyenera kwambiri kukongoletsa bwino.

Gulu la gypsum

Mu gypsum boarch kupanga, HPMC imagwiritsidwa ntchito kwambiri kuwongolera kuchuluka kwa hydration, kuletsa bolodi kuti lisafoke mwachangu, sinthani mtundu wa zomalizira, ndikuwonjezera kukana kwake.

Gypsum okha

HPMC imatha kusewera ndi zida zamphamvu mu gypsum zodzikongoletsera zodzikongoletsera, kuzipereka bwino komanso kukhazikika, kupewa tsankho komanso kukhazikika, komanso kusintha mphamvu yomanga.

3. Momwe Mungagwiritsire Ntchito HPMC

Pali njira zotsatirazi zowonjezera hpmc kwa gypsum:
Mosakaniza molunjika: Sakanizani HPMC mwachindunji ndi zida zouma monga gypsum ufa, ndikuwonjezera madzi ndikuyambitsa bwino pomanga. Njirayi ndiyoyenera ku gypsum yothina-yosakanikirana, monga gypsum putty ndi zoyala.

Onjezani pambuyo pa kusungunuka: Sungunulani HPMC mumadzi mu colloidal yankho la colloidal poyamba, kenako kuwonjezera pa gypsum slurry kuti ithetsedwe bwino. Ndioyenera kupangidwa ndi zinthu zina zapadera.

4. Kusankha ndi kuwongolera kwa hpmc

Sankhani mafayilo oyenera

HPMC imakhala ndi mitundu yosiyanasiyana ya ma viscccle, ndipo ufa woyenera ungasankhidwe molingana ndi zosowa zapadera za mankhwala a gypsum. Mwachitsanzo, mafayilo apamwamba a HPMC ndioyenera kuchulukana kotsatsa ndi anti-sagging, pomwe otsika-viscked hpmc ndioyenera kwambiri ku Gyplum ndi madzi ambiri.

Kuwongolera koyenera kwa kuchuluka kwa kuwonjezera

Kuchuluka kwa hpmc komwe kumawonjezera nthawi zambiri kumakhala kotsika, nthawi zambiri pakati pa 0,1% -0.5%. Zowonjezera zochulukirapo zitha kukhudza nthawi ndi mphamvu yomaliza ya gypsum ya gypsum, motero iyenera kusinthidwa mogwirizana malinga ndi machitidwe azogulitsa komanso zofunika zomanga.

Hydroxypypyl methylcelluloseImagwira ntchito yofunika kwambiri m'magulu a gypsum. Sizongosintha madzi osungira komanso zolimbitsa thupi, komanso zimathandizira motsatsa komanso kukana zinthu zina, kupanga gypsyam zinthu zambiri zolimba komanso zolimba. Kusankha koyenera ndikugwiritsa ntchito HPMC kumatha kusintha zinthu zabwino za gypsum ndikukwaniritsa zofunikira zosiyanasiyana.
